Review conclusionWith reservations—

Only in one review: Voltage 12 V (12 V 60 W power supply); Ripple 150 mV (12 V 60 W power supply); No load 0.1 W (12 V 60 W power supply); Protection 8.3 A (12 V 60 W power supply); Temperature rise 58.6 °C (12 V 60 W power supply).

12 V 60 W power supply: Essentially a sound 60 W supply with acceptable ripple and temperature, but its protection current is much too high.

12 V 5 A uninterruptible power supply: Good as a power supply and lock controller, but its battery charging and discharge protection need improvement.

Figures were taken from the review text and checked against the quoted passages. Measurement conditions differ between reviews, so read the reviews yourself before buying. Prices at the time of review.
